First time hearing a Moduator, and I will say it was a bit punchier than the old Whelen 3016 in Bedford Park. I initially thought they would do two wail cycles rather than four 10 second blasts, but hey, that mean more footage! Not much else to say here, other than that I will be stuck with these and 2001's for a while (oh how I wish I could go back in time to when they had the thunderbolts and 2T22s!). Enjoy!
